# Monarca Minerals Reports Final Drill Hole Assays from Phase 1 Exploration Drilling at San Jose Project - Including Significant Molybdenum & Copper Values Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/monarca-minerals-reports-final-drill-hole-assays-from-phase-1-exploration-drilli--b311f2b8-5caa-403a-bea7-a4420c4cb89d Original source: https://money.tmx.com/en/quote/MMN/news/5231005240648112/monarca-minerals-reports-final-drill-hole-assays-from-phase-1-exploration-drilli Publisher: tmx Original announcement: 2021-12-14T13:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Monarca Minerals, Inc. - Ticker: MMN - Exchange: TSX - Region: Mexico - Primary commodity: Copper - Secondary commodities: Molybdenum, Gold, Silver, Lead, Zinc - Document categories: Drill results - Extracted: 2026-08-23 22:53:21 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Monarca Minerals has released final assay results from its Phase 1 exploration drilling at the San Jose project in Mexico. The results confirm significant copper and molybdenum mineralization, particularly in skarn-related environments, and highlight exploration potential to the west of the current drilling. Reasoning: The release reports final assays from Phase 1 drilling, confirming significant Cu and Mo mineralization and identifying skarn potential, though true widths are not yet established. - Positive factor: significant Cu and Mo mineralization - Positive factor: skarn potential identified - Positive factor: QA/QC disclosed - Negative factor: true widths unknown - Negative factor: exploration stage Facts used in scoring: 22 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions ISO Accredited laboratory, blanks, standards, and duplicates. Evidence · text > Procedures have been implemented by Monarca to assure Quality Assurance Quality Control \(QAQC\) of all assaying that was done at an ISO Accredited laboratory. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: Note states true widths are unknown due to insufficient drilling. Evidence · text > True widths are unknown at this time due to insufficient drilling. ## Extracted facts Stored fact records: 22. Some facts used in scoring do not have a stored record. ## Drill Results (22) ### SJ02 [Link to this fact](https://atlas-staging.minestarters.com/news/monarca-minerals-reports-final-drill-hole-assays-from-phase-1-exploration-drilli--b311f2b8-5caa-403a-bea7-a4420c4cb89d#fact-drill-facts-0) San Jose · copper #### Identity - Hole ID: SJ02 - Project: San Jose - Commodity: copper - Ticker: MMN #### Geometry - Grade: 1.02 - Grade Unit: % - Intercept: 1.5 m #### Classification - Sample Type: drill - Group ID: SJ02:null-null #### Review - Needs Review: No - Interp.
